              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
The night started with bands of thicker and thinner clouds, and some approaching precipitation.  But the clouds kept getting thinner and the precipitation passed to the south of the observatory, and we ended up with a fairly productive night.  After some software restarts in the afternoon I had to do some work to get dcam talking, and we also managed to bring Tspec back (although the slitviewer is still awaiting a part, due to arrive on Tuesday).
